We hold Siemba to the same standard we test you against.
We hold Siemba to the same strict security standards you expect from your own environment.
Big 4 and global consulting firms bring us in to pentest their government and enterprise clients.
Join Our Partner ProgramThe vendor you bring in to reduce risk can quietly become your biggest one
Security testing is an act of trust before it's anything else. Choose the wrong partner and the very engagement meant to protect you turns into the exposure you never planned for.
Attack-level access
Pentesting means real credentials, source, and infrastructure exposure. In careless hands, that access is a breach path in its own right.
A map of every weakness
A findings report is a blueprint of exactly how to compromise you. Where it's stored, who sees it, and how long it lives should never be a mystery.
Unknown hands
Crowd-sourced and offshore models put anonymous testers inside your environment. You can't trust what you can't identify.
Security isn't a checkbox. It's the culture we operate on
A security company should be held to a higher standard than the ones it audits, not a lower one. These four commitments govern how we build the platform and how we run every engagement.
Secure by design
From architecture to deployment, prevention and validation are built into every layer, not bolted on afterward.
Transparency wins
Audit logs, risk reports, remediation timelines. Visibility builds trust, so you always know exactly where you stand.
Continuous improvement
Security is never static. We evolve, adapt, and strengthen our own posture in real time, the same philosophy our platform runs on.
Accountability
Compliance alignment and third-party validation aren't optional. We operate with integrity in every engagement, in writing.
What we promise, in plain terms
No hedging, no fine print you have to hunt for. Here is exactly how your data is handled, who touches your systems, and how we keep testing safe.
Handled on your terms, then gone
- We never train models on your data. Your systems, findings, and traffic are never fed into model training, ever.
- All AI runs inside our own AWS environment. Your data is never sent to a third-party model, for training or inference. Nothing leaves our boundary.
- Your data is logically isolated from every other tenant in our multi-tenant platform.
- Free-scan data is kept 30 days, then removed automatically.
- After a contract ends you get a 90-day export window, followed by attested destruction of your data.
- Data lives in AWS US by default, with EU and APAC residency available on request.
Named, in-house, certified
- In-house testers only. No anonymous crowd, no offshore hand-offs. You know who is in your environment.
- Big-4 backgrounds holding OSCP, CPENT, and CEH certifications.
- Every tester is background-checked before they touch a customer environment.
- Every engagement is delivered by Siemba-certified professionals, the same team behind the platform.
Aggressive on findings, careful with production
- We never brute-force production systems without your explicit written permission.
- Scope is agreed before we start, and findings are published in real time so nothing is a surprise.
- Verified Closure: we retest every fix and confirm it actually holds, so remediation is proven, not assumed.
Automation with a permission boundary
- MCP access is scoped and permissioned. Any action taken through our MCP integration stays inside the boundaries you set.
- Every automated action is logged and auditable, so an AI-triggered test is as traceable as a human one.
- Human oversight stays in the loop on scope, targets, and anything that touches production.
We hold ourselves to what we test you against
- Siemba is independently penetration-tested by a third party. We put our own platform through the same scrutiny we bring to yours.
- Data is encrypted in transit and at rest: TLS 1.2+ in transit, AES-256 at rest.
- We notify you promptly of any security incident affecting your data, in line with the terms of your agreement.
Recognition that's earned, not self-declared
